Christians often think of the Old Testament as focused on the Father in the way that the New Testament is focused on Jesus, but they’re wrong. The Old Testament focused on the First Person of the Trinity as Creator and Judge. While fatherhood is hinted at, we don’t really come to know Him as our Father until Jesus shows us how.
Everywhere the news of Jesus spread, certain things inevitably followed. Once Jesus showed us what God is really like, it became much harder to worship angels. Once Jesus showed us what incarnate God is really like, we became unable to take “divine” kings seriously, and they slowly ceased to be. Likewise, Jesus showed us the Creator as our Father, and this gave us a standard by which to measure human fathers.
Your father might have been great, or terrible, or somewhere in between, but he certainly wasn’t perfect. When you meet God the way Jesus shows Him to us, you meet a Father who covers the gaps your father left, whatever they might be. He stands ready to restore what was lost. But don’t take my word for it: let Him show you. Merry Christmas!
